WARNING: The [.Accept] file is deprecated, use the [.Buckets] file instead.


Restrict what can be dropped on app instances. Accepting means allowing a file to be dropped into an instance.

One of the following file types must be used with an .Accept file:

Examples use cases

A gallery app may want to disallow dropping anything but images into it. A 2-column splitter app may only want to accept anything that can be inlined into a web page.

The .Accept file allows you to set these restrictions.


If the .Accept file does not exist, the app will default to not accept anything.
